Aquarium for Heros
specimen of Heros are substrate breeders, with the exception of Heros
severus, that, after they have been laid, takes the eggs in the
mouth to let them hatch out there. So tat is a larvophile mouthbreeder.
When it concerns the dimensions they are well matched. They differ between
20 and 25 CMS. They all are peaceful animals, that can be kept together
with their own sort and/or other fishes without problems. Only in matingseason
they turn nasty against their own sort. Keeping together of more than
on couple, in a large aquarium is than impossible without occurring
phenomenon's of stress. One pair comes to power in the group and all
the others are chased and ousted. Real heavy injuries don't occur but
the animals don't come by the feed any more and pine away finally.
The best way to obtain a good breeding pair
is purchasing a fair number of young animals and let them grow up together
in their future quarters. About seven or so. This has as an advantage
that good pairs can be selected. Animals that remain behind in there
growth or in an other way show ailments can be eliminated. So there
is a convenient chance a harmonious couple will come into being that
exits of well developed animals. It goes without saying that for this
a spacious aquarium is needed. In our case a tank of 230 cm long x 110
cm broad x 65 depth. The selected animals later on can mostly be sold
for a good price and in this way compensate a little the costs of the
purchase. At first the population existed of 3 couples of Heros notatus
and 18 Corydoras
melanistius melanistius originating
from the area of the Heros, scratched around
on the bottom. A couple Apistogramma spec. were left Undisturbed.
the vegetation consists of two large groups of Hydrocotyle leucocephala
and Nymphoidesaquatica being rooted in the bottom and the
leaves as umbrellas on to long stems at the surface. On the foreground
another field of Sagittaria subulata and the picture is complete.
The floating leaves bring shadow.
